WarningThe VLS-07 is designed to be a warning device for vacuum leakagedetection. When properly installed on an ANVER vacuum lifter, theoperator will be warned of a slow vacuum leakage and should haveadequate time to safely lower the attached load. If the alarm signal isignored and the lifting operation is continued, the vacuum loss mayadversely affect the vacuum "hold", possibly resulting in serious injury
to the operator. The VLS-07 is not designed for nor effective indetecting fast leaks or sudden failures of the vacuum system.
Vacuum Leakage Sensing Systems
VLS-07 Vacuum Leakage Sensor
Principle Of OperationThe VLS-07 Vacuum Leakage Sensor is a vacuum level differential detectorwhich is pre-programmed to activate the alarm at a 10% reduction invacuum with a leakage rate of less than 1.5 inches Hg per second.The alarm will continue until a sufficient increase in vacuum is achieved,indicating no additional leakage is present, or the indicated vacuum leveldrops below 5 inches Hg. The horn, LED (red light) and LCD (digital
display) can be tested by pressing and holding the "Test Button" forapproximately 3 seconds. The unit is also equipped with a low batteryindicator which will cause the horn to "chirp" and the LED to flash whenbattery power is low. The battery should be replaced immediately with astandard 9V lithium battery. The auxiliary output jack on the VLS-07 is anopen collector output which can be connected directly to the VLS-07-AUX-S(auxiliary siren/strobe), or to another 1/0 device, such as an emergencystop function on a CNC control, through a solid state relay. The unit isprovided with Mounting Holes for 4 #10 Self-Tapping Screws.
The Latest in SolidState VacuumLeakage Detection
The VLS-07 monitors the vacuum levelautomatically. If vacuum is lost during alift a loud horn sounds, and a red lightflashes to warn the operator.The VLS-07 monitors vacuum level evenif the operator is not looking at thelifter,a useful and popular option.
The VLS-07 is a battery powered unit
consisting of a pressure sensor, an audible
warning horn, red warning light, and test
switch, all controlled by a solid state
microchip. All ANVER Vacuum Lifters,
Vacuum Tilters and Specialty VacuumLifting Machinery can be equipped with a
VLS-07 Solid State Vacuum Leakage
Sensor and Warning System. The system
is packaged in a rugged polycarbonite
enclosure with a 1/4" push-to-connect fitting
for tubing connections.
During each lifting cycle the programmed
'intelligent' processor senses the peak
vacuum level. From this point, a 10% loss

of vacuum with a leakage rate of less than
1 in. Hg per second from that peak level
will trigger the horn and light, informing the
operator of a leak. The alarm will not sound
on the detach cycle as with other primitive
systems using preset switches. Even the
smallest leak anywhere in the system will
be detected. The VLS-07 system
automatically monitors the vacuum level fo
the operator.
